COMBINATION RANGE.

Application filed June 24, 1920. Serial No. 391,275.

To all whom it may concern:

Be it known that I, THEODORE J. MIGOHEL- 'BRINK, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Combination Ranges, of which the following is a full, clear, and exact description.

This invention relates to a combination coal and gas range.

One of the objects sought by the present invention is to provide a range of the character described, in which what is known as an elevated oven may be heated either by means of a gas burner or by the heated gases from a coal fire.

A further object of the invention is to provide a structure for the purpose in which the flue passage around the oven is con.- trolled by a damper which opens the flue to the products of combustion from the burner and closes the flue with respect to the coal fire box or vice versa.

Reference should be had to the accom- 5 panying drawings forming apart of this specification, in which Fig. 1 is a front elevation of a range embodying the present 111-.

vention; Fig.2 is an elevation with portions in section; Fig. 3 is a transverse section and Fig. 4, is a top plan view of a portion of the range; Fig. 5 is a front elevation of a modified construction.

Referring to the drawings, 1 indicates the top or anchor plate of the stove, 2 indicates the fire box and ash pit, which .is closed by a door 3. At 4 is indicated the oven portion which is closed by a suitable door 6 and beneath the oven 4 is a broiler compartment which is closed by a suitable door 6.

The portion beneath the top 1 of the stove is an open space which isindicated at 7, this open space being entirely enclosed and :is adapted to contaln gas burners such as 1nd1- cated at 8, the connecting pipes for which extend through the frontwall'l and communicate with usual valve structures such j as indlcated at 8 which in turn communicate with'a gas header pipe 9. The space 7 is in open communication with the tire box 10, which fire box is provided with the usual is a gas burner 23 the damper is in closed position;

lining 11 and a grate 12 at the bottom portion thereof. Beneath the grate 12 is the ash pit indicated at 13.

The oven proper is indicated at 14 "and. is supported by the front andrear walls of the stove structure, following usual construction.

Beneath the oven 14 is a flue 15 which communicates with an end flue 16 and this line in turn communicates with a top flue 17. The flue 17 communicates with a flue space 18 which flue space at its lower end is closed by a wall such as indicated at 18*. The back wall which bounds the flue space 18 is provided withan opening 19 which communicates with the flue pipe 20 carried upon the back of the range.

The walls which enclose the broiler space 5 are provided with an opening such as indicated at 21 which is at the end of the flue15.

Pivoted adjacent one edge of this opening is a damper 22 which isso pivoted that p it may be movedto cover the opening 21 or moved downwardly as shown in Fig. 2 for across and engages the wall .43 thereby closing the communication whichthe fire box 10 normally has with the flue 15.

Within the broiler compartment 5 there This gas burner-extends adjacent the edge of the opening 21 and is so positioned that the flame from the burner is directed through the opening 21 when the same is uncovered; This burner 23 is connected by gas header 9.

At the end of the flue 17 there is a damper as indicated at 24. This damper is pivotally mounted along one of its edges as indisuitable pipes with the cated at 25 and is adapted to'extend across the fine 18 where it joins the line 17, when The damper does not extend through the entire length of the flue 18 as is seen from Fig. 4, but leaves aportion of this flue open even when the damper is in closed position.

This damper 24 is in closed position when the damper 22 is in open position or in other words, when the opening 21 is uncovered and gas is being used. The damper 24 thus partially reduces the flue space when gas is used, which is a desirable feature as in the use of gas the same area of flue is not required as when burning coal.

For the purpose of easy operation the damper 22 is connected with the damper 24 by means-ota rod 26 which extends through the flue pipe 20 :on the back of the range. The connection is such that when the damper 22 is operated, the damper -2i'is also operated. The damper 22 may be turned by means of a handle 22, which extends upon the outside of the front plate of the stove.

As will be seen by reference to Fig. 2, the hot gases either from the gas'burner or from the tire box when a coal'fire is used, pass substantially entirely around the oven 14 so that it is heated on all four sides thereof. This results in producing a very uniform temperature in the oven and creating .a desired oven temperature very rapidly after the application of heat is started.

The anchor plate 1 of the range is provided With the usual openings, but .these are closed by means of covers such as indicated at 1 when the range is used as .a coal range thus enclosing the space 7 and the anchor plate 1 becomes heated by the products of combustion from the fire .box in the same ananner .as in .the usual types of .coal ranges. During the use of the range as a coal range, the burners remain in place.

When the range i flbeing used as a gas range the covers 1 may be replaced :the usual vform of grids which [permits the flame from [the gas burners to be utilized in heating receptacles placed on the grids, in the usual fashion.

As will .be noted, the fire box is located centrally of-t'he range rather than at one end as is the usual custom. This arrangement is purposeful in that it permits the passage of the hot gases from the tire :box

directly through .the flue surrounding the oven so that there is practically .a direct application of .heat to the :oven.

This construction may be varied, as in dicated in Fig. In this figure the fire box 30 isflocated at one end of the range and communicates with a chambered portion indicated at 31 and this chamber in turn communicates with a vertical flue 32 which is controlled by damper 33 which also controls :the opening 3% in the wall and adjacent the opening 3a is the oven heating burner 36,.

covers, as well as the burners located in chamber 31 are precisely the same as before described.

At one side of the fire box and beneath the broiler compartment, is a hot closet which is closed by a suitable door as indicated at 37.

VVhena coal fire is used, the heated gases pass through the chamber 31 and thence to the tines around the oven.

Having described my invention, I claim- 1. In a range, an anchor plate for said range, an oven located above said anchor plate, a casing surrounding the said oven thereby providing a flue for the passage of heated gases, means providing a compartment beneath the saidoven, a gas burner located at one side of said compartment, the said broiler compartment being provided with an opening into the flue adjacent the oven whereby the products of combustion from the gas burner may pass to the flue surrounding theoven, said gas burner being adjacent the opening and adapted to direct a flame into the opening.

2. Ina range, a fire box, an oven located entirely above the fire 'box, a casing surrounding the oven and providing a fine for the passage of gasesaround the oven, means forming a connecting passageway between said flue and the firebox, a gasburner located adjacent one end of the said time, there being an opening in the wall of said connecting passageway adjacent the burner into which the burner is adapted to project a flame and through which products of combustion may pass from the burner to the flue, amovable damper inthe connecting passageway which controls said opening.

3.. Ina range, a fire box, an oven located entirely above the embox, a casin surrounding the oven and providing a .ue tor the passage of ggases around the oven,

means. forming .a connecting passageway be-' tween said flue and the fire box, a gas burner located ad acent one end of the said flue, there being an opening in the wall of said connecting passagewaythrough which products of combustion may pass from the burner to the .flue, a damper located in said connecting passageway and movable to one position to close the said opening adjacent the gas burner and. movable to another position :to uncover said opening and close the connecting passageway with respeot to the firebox.
